Atlantis PQ is a BP and BHP joint venture semi-submersible oil platform on permanent location over the Green Canyon Atlantis Oil Field in deepwater Gulf of Mexico, south of New Orleans. The "PQ" identifies the platform as being a production facility with crew quarters. The vessel's hull was designed by GVA and built by Daewoo Shipbuilding & Marine Engineering (DSME) in Okpo, South Korea. Its topsides modules were built in Morgan City, Louisiana with hull integration in Ingleside, Texas. Operating in depths of more than , Atlantis was the deepest moored semi-submersible platform in the world when it was installed. Food & Water Watch lawsuit As a result of the 2010 explosion of the semi-submersible Deepwater Horizon drilling rig and the subsequent oil spill, informants within BP came forward with allegations that safety practices at Atlantis PQ were flawed. Specifically, allegations have been laid against the plans and specs used in its construction, maintenance, and operation. Kenneth Abbott, a former BP contractor, reported that up to 89 percent of the engineering plans used to build and operate the installations were never authenticated by even BP engineers for safety and stability, and that over 95 percent of the plans for the underwater welds were never verified. Food & Water Watch, a US-based consumer interest group, filed a complaint with the US district court requesting an injunction to stop production on Atlantis PQ until these matters have been investigated. In August 2014, the case against BP Atlantis was dismissed by a U.S. circuit court. U.S. District Judge Lynn N. Hughes stated "BP never misrepresented -- much less knowingly distorted what it was doing,", finding that the case was ultimately about "paperwork wrinkles" instead of engineering shortcuts, adding [Abbott and the environmentalists] "have not blown a whistle," he said. "They have blown their own horn."
